Looking for a chill strain that doesn’t skimp on strength? Critical Purple Auto brings deep relaxation, earthy-sweet flavour, and hassle-free growing all in one compact, high-impact package.
Looking for an autoflower that’s not just pretty in the pot but hits like a freight train on a velvet track? Critical Purple Auto checks every box. This strain’s got knockout potency, a compact frame that works wonders in tight spaces, and dense, frosty buds that smell like a walk through citrus groves after rain (if those groves also happened to grow hash). A cross of Critical Mass, Big Bud, and Ruderalis, this fast-flowering indica-leaning hybrid was built for growers who want maximum impact without the long wait. And when harvest rolls around? She doesn’t just show up, she shows off.
The lineage here is a greatest-hits mashup of high-yielding royalty. Critical Mass and Big Bud are both known for their heavy-handed productivity, so it’s no surprise Critical Purple Auto inherited that "stack ‘em high" mentality. Add Ruderalis to the mix, and you’ve got a strain that flowers on its own schedule but still carries the punch and perfume of her heavyweight photoperiod parents.
Expect a blanket of full-body relaxation that starts in the shoulders and melts its way downward, leaving a trail of heavy limbs and slowed thoughts in its wake. This isn’t a strain you toke before a hike. It’s more for movies, munchies, and maybe a nap you didn’t plan on. It leans toward the sleepy side, but there’s just enough mental clarity to keep you functional, if not exactly ambitious. Flavour-wise, it’s got that earthy-sweet baseline with a woody warmth and a citrus zing on the back end, like a lemon drop rolled in potting soil (in a good way).
This one hits surprisingly hard for an auto, with THC levels up around 25%. CBD stays low, at around 0.70%, which means the buzz is largely psychoactive. Expect that classic indica couch-lock creeping in if you push past moderation. Not for first-timers unless you're ready to be humbled.
Limonene brings the citrus pop. Linalool adds a soft floral sweetness. Pinene lifts the whole experience with a slightly herbal clarity. Then beta-caryophyllene rolls in with its spicy backbone, grounding the aroma in something you can almost chew on. It’s a terp combo that leans warm and soothing but still leaves room for complexity.
She’s beginner-friendly, especially for those still getting their hands dirty with autoflowers. The compact stature and built-in flowering clock make her a low-maintenance choice, but the yields and bud quality don’t feel like beginner weed. This is the kind of plant that makes you look more experienced than you are.
Indoors, she stays nicely compact at around 50 cm to 90 cm, so she’s a natural fit for small tents or stealth setups. Outdoors, expect a little more stretch, with plants reaching 60 cm to 120 cm in ideal conditions. Thanks to her ruderalis genes, she handles fluctuations in light and temperature better than fussier strains. That makes her a great option for less-than-perfect climates or greenhouse grows.
Flowering kicks in fast, and she usually wraps things up in just 49 to 56 days from the start of flowering. Indoors, you’re looking at solid returns of around 300 to 400 gram per m2. Outdoors, she’ll reliably push out 150 to 200 gram per plant if given decent conditions and a bit of care. Not bad at all for a compact auto that doesn’t waste time.
If you’re after a high-THC autoflower that doesn’t mess about, Critical Purple Auto is your girl. Fast, potent, and stunning in bloom, she delivers classic indica effects with autoflower convenience, all wrapped up in a sweet, citrusy, earthy package. Order your feminised seeds now and see just how far this compact powerhouse can go.

So far out of the 20 I ordered I have planted 11. I started with 3 right away. 2 hermied near the end but still produced and 1 was great! So next I put up a brand new tent and started with 3 again and one more hermied almost right away. The other 2 look amazing currently. I'm using geoflora in coco coir / promix with 6.8 ph water. I'm monitoring my vpd. I'm beginning to think I just got bad genetics. I'll update my review when the rest that I just planted are done
